i have answered, like i said before, i just shared what i read and hear.....im no military expert.......i standby with my information....which is tejas HAVE ENDURANCE issues meaning it can only do 1 hr flight as of today, which they seem to correct with the mark-2 design atleat on paper.
Now regarding which old engine they had (before they replace it with this America engine that they have right now) or not is irrelevant to me nor do i know myself.......This mach 1.1 speed was shared on this video along with the source of that news which was Tejas own official website. It is pertinent to remind u that this wasnt my original claim........The reason why i shared this video was that it does give u reasons for its endurance issues ie overweight and it being too late.
U can watch that video again to recheck the sources or ask the guy who has made this video.
My point still stands, abt its endurance and only 1 hr flight time. Now for what reasons it had being overweight or speed, are just people trying to find reasons behind it....... That is of no real interest to me, but as a researcher it might be of yrs interest so i leave that to yr judgement and to find out for yrself. The depth of my knowledge as a civilian ends here.
Thats all authentic information i had buddy...rest are just my assumptions and connect the Dots, thats upto u to buy or not.
The authentic info. that i still standby is its 1 hr flight time in its current mark1/1A versions.
